The Iron Man Movies and the Engineering Design ProcessBillionaire genius and weapons designer Tony Stark is captured
by terrorists, and they want him to build a super-weapon. Instead he builds an armored exoskeleton to fight them.
1st PrototypeMark 1 Version
3rd PrototypeMark 3 Version
Notes SPI 0807.T/E.1 (Prototype Testing)SPI 0807.T/E.2 (Eng. Des. Process)
Step 1: Identify a need Why did Tony Stark build the "Iron Man" suit? Step 2: Develop Possible Solutions What are some other options he could have built instead?
Step 2A: Pick the best design Do you think the "Iron Man" suit was the best design option?
Step 3: Make a prototype Where and how did Tony build his prototype(s)Step 4: Test the prototype Where and how did Tony test his prototype(s)Step 5: Modify and re-test the prototype How did Tony modify his prototype to make it work better?
Step 5A: Use and/or sell the product Did Tony sell his Iron Man armor? How did you use it?

Engineering Design Process Science
Which step of the engineering process is this?
STEP 4:Test and Evaluate
Intended Purpose/Consequences: When a company designs a new product, they are addressing a need.
(This is Step 1 of the engineering design process).This need is connected with and is essentially the same as the intended purpose. The intended purpose/benefit is what the engineers purposely include when designing some product or process.
NotesSPI 0807.T/E.3
Intended Benefits and Unintended Consequences
Science
Example: Cell phones -The need being addressed is communication. Likewise the intended purpose is more effective communication.
What is the intended purpose/benefit?
Another Example: Automotive Technology
(cars and trucks)
Unintended consequences: …are uses or results that engineers DO NOT purposely include when designing some product or process.…these are things that WERE NOT part of the design plan.
NotesSPI 0807.T/E.3
Intended Benefits and Unintended Consequences
Science
Example: Cell phones and Cars -One unintended consequence is wrecking your car while talking or texting while driving.
Cell phones and cars were not designed to cause traffic accidents
Intended benefit -cell phones were designed for communicationIntended benefit -cars were designed for transportation
